“My tomato plant looked fine yesterday. Today, it’s GONE!!” To***co hornworms and tomato hornworms attack tomato plants and occasionally peppers or eggplant.
The distinctive horn on the rear of the body makes this large, green caterpillar easy to identify. The species most commonly seen on tomatoes in Mississippi is the to***co hornworm, which usually has a reddish horn and seven white diagonal stripes on the side.
The tomato hornworm usually has a black or green horn and white V-shaped marks on the side. Mature larvae may reach 4 inches in length, and caterpillars of this size can quickly consume large amounts of leaf area.
Occasionally these caterpillars feed on fruit, but defoliation is the major type of injury. You rarely see the large, gray, night-flying moths. These jet-shaped moths lay their large, shiny eggs individually on the leaves of host plants.
As for management practices in small plantings, consider hand-picking eggs and caterpillars off the plant and disposing of them.
